Arduino based CPU temperature sensor

There are times when our computers overheat for a good many variety of reasons. In the case of Taylor Niver who just bought a new graphics card for his computer, the GPU started overheating due to his power supply not being large enough to provide enough juice to power his new graphics card properly. Deciding that he did not want another close call and a potentially burnt out GPU, he came up with his own temperature monitoring system.

The system basically made use of Arduino, a general purpose temperature sensor and an RGB LED light. The Arduino is hooked up to the temperature sensor, which is placed near the GPU in order to monitor its temperature. The RGB LED light is an indicator to let him know when his GPU starts experiencing higher than normal temperatures. In his case, he set the threshold at 50C. Should the temperature rise above that, the RGB LED will turn red, indicating an overheat, but if everything is normal the RGB LED will show a blue hue instead.

If this is something you wouldn’t mind setting up for yourself, head on down to Taylor Niver’s blog where he provides instructions and even the code that he used to make it all happen.
